WINDOW CONSTRUCQIION.

Specilcation of Letters Patent. Application led August 24,' 190g. Serial No. 514,353.

' Patented July 5, 1910.

To all whom fitmay concern:

Be it known that I, ALFRED J. ELLIS, a citizen of the United States, residin 'at Woodclif-on-Hudson, township of orth Bergen, in the county of Hudson and State i of New Jersey, have invented certain newj and useful Im rovements in Window Con-f struction, of willich the followingis a full,:

My invention relatesto window construcg tions, more particularly high grade win-gy dows lfor-oflice buildings, hotels and dwell-g1 ings, Where the requisites of easy manipulation andgtightness against wind and weather,'

together with permanence or durability inf `the foregoing qualities are especially de-; sired.

The invention employs sheet metal as ag basis of the structure, this material beingV drawn or otherwise formed into special out-I lines which .secure the features and prin,l ciples hereinafter described.

A difficulty with prior constructions has been in the matter of obtainingsuiiicient Ito tig tness against 'wind and weather with- 'out sacrificing easy running qualities, it being evident that all forms of yielding packing such as a rubber weather strip, imposel considerable friction on the sash and interferevwith its free movement.

It is a prominent object of my invention avoid all .formsof yielding packing and obtain all the wind and weather reslsting qualities desired, without imposing any appreciable eXtra friction or resistance tod the movements of the sash. I have furthermore i provided for great permanence or durability 1n the above mentioned functions or purposes, the ywindow retainin its wind and weather tight, qualities an easyrunning qualities regardless of continued wear, an further regardlessof any sort of changing .weather conditions, l those which produce swelling or changes such for example, as

of form in ordinary wooden frame parts.

A still further object of the invention is to 'provide a window which is reproof and ornamental in appearance, and suitable for the exacting requirements of the high grade purposes for which it is designed to be used.

With the various foregoing and other objects in view my invention consists in the features of construction and combination as claimed..

. lower sash of mental facing for the metal, however, does Iing for the wood, but has separate structural of a window construction embodying the :principles of my invention. Fig. 2 is a vertical sectional view. Fig. 3 is a transverse sectional view through one side of the same. Fig. 4 shows a detail.

Referring to the drawings in which like p arts are designated by the same 'reference sign, 1 denotes the upper sash and 3 the a window, 2 being the window frame. This frame comprises a head 4 at the top, a sill 5 I 6 on each side. t

7. denotes a molding serving as an ornaoutside of the window frame in the usual way.

'In accordance with the present invention,

g each jamb 6 has a parting bead 8 extending from the top to the bottom thereof and which I construct of sheet metal, preferably drawn orl formed on a of rectangular transverse section. The sheet notmerely form a coatfeatures of its own, entirely apart from the characteristics of the core, and which form an important part of the present invention.

`I referto the ribs 10 and 11 which project respectively to one side and the other of the parting bead at the front face thereof `and which 'are produced by laterallyextending flat foldsof the metal -coincident with the plane of its front face. The rib 10 `coperin practice I make the upper section of the parting rail of an entirely separate piece of sheet metal lfrom the lower part, folding theC metal i at the upper part with a rib 10 on one side and the metal on the lower part with a rib l1 on the other side, the two parts being lapjointed together and soldered over the continuous wooden core. In this Way the rib l0 of the'upper'part of the bead over-laps for a distance of a gfew inches the rib of the lower part of the parting bead. This overlap amounts to about the normal over-lap of the upper and lower window sashes.

he upper sash l has an upper' rail 12. also formed of sheet metal which is, preferably drawn or formed on a vwooden cpre. It will be understood that the provi-sion of a core of this sort is not an essential but is merely a convenient construction; the sheet metal may be left hollow if desired, or supplied .with any kind of. interior ller. In

vsolid wooden core 9/75 `ates with the upper sash and the rib'll withI y 'the lowe'i` sash, as later described.

65 y at the bottom,and a jamb t accordance with the present invention I fold the sheet metal of which the upper rail is composed with a tongue 14 on lts` to side, this tongue extending parallel wit the length of the rail and standing up in a vertical plane. The sheet metal offwhich this tongue 14 is' composed is tightly drawn or pressed into a fiat fold so that the resultant tongue is hard, rigid and slender, with a total thickness not exceeding twice the thickness of the sheet metal employed. In these res ects this tongue is similar to the ribs 10 an 11 of the parting bead already described.

15 denotes a sheet metal facing on the under side' of the head 4, and this facing is formed with a narrow deep groove 16 having a position and alinement adapted to receive thetongue 14-when the upper sash is fully elevate The side rails 16 of the u per sash are constructed of sheet metal e the upper rail, except that in place of having a tongue 14, these side rails are each formed with a deep narrow groove 13 adapted to receive the rib 10 of the parting bead. In case a wooden core is used the metal is inply drawn or pressed into a` deep groo e vof the core, thereby establishing a nar w`Yv channel of jut about the width of the corresponding ri 10.

Thelower sash is similar to the upper sash, having side rails 17 with grooves 18 to receive the ribs 11. The lower rail of the lower sash also has an interlocking engagement withthe sill formed by a tongue 19 and groove 20 similar to the tongue and groove 14, 16 of the upper rail and head, except that in the lower sash the tongue is on the sill or stationary frame part and the window rail has the groove. It will be understood that either arrangement is within my invention in any part of the window structure, one'being merely an obvious reversal of the other.

Each window sash .has a meeting rail denoted 21 and 22 for the respective upper and lower sashes. These meetlng rails are also of sheet metal preferably drawn or formed on a wooden core, and each has a groove 2? and a tongue -24 respectively coperating in -the manner shown in Fig. 2. These tongues and grooves are constructed in the same manner as the tongues, ribs and grooves already described. The meeting faces of the meeting rails are inclined with respect to one another so that as the sashes ap roach their normal closed positions, the sai faces press against one another with anincreasing tightness of engagement, and Vat the same time their respective tongues and grooves interlock, as shown, thereby providing a double seal against any passave ofair, in addition to the seal which is effected by the wedging together of the inclined faces.

Lsliding fits.

ceases n will be observed am um foregoing window construction secures all the functions and advant esmentioned in the preliminary part'of t. iisv s iceication. Aiwind and weather tight seal 1s established atevery point and on all sides, but the charac er of the engagement is such as not to obstruct perfect freedom of movement of the sashs. The upper sash slides up and down in the jambs with the ribs 10 continuously interlocking with rooves 13. Correspondingly, the lower sa slides freely up and down with the ribs '11 continuously interlocking with the grooves 18. Inasmuch as these ribs are closely folded and compacted and hard drawn, they are very stiff and rigid as wellY as straight and uniform in cross section. They are not liable to swelling or expansion or any change `of form by use or weather conditions. The same istrue of the grooves in which the said ribs are received. Under these circumstances freedom of movement and at the same time atight fit are permanently insured. The various tongues 14, 19 and 24 which are brou ht into their grooves by being longitudinal y projected thereinto at the completion of the sash movement, are accurately guided by virtue of the tightness and accuracy of the These tongues may therefore be made to engage with ythe same closeness and accuracy as the sliding ribs. The completed window construction therefore serves all its purposes with complete and unvaryinfg etticiency throughout, and regardless o continued wear or any sort of. unfavorable weather conditions.

What I claim, isha e e 1. A window construction com risin a .t

window frame having arting bea sas es having meeting rails, t e opposed faces of which are inclined and directly en ageable with each other substantially over t e1r en-` tire extent, and interlockin grooves on said faces, sai tongues and grooves being wholl formed of sheet metal 'and having the sur aces thereof stepped lto afford a plurality of engaging surfaces.

2.
